Undertow Core HTTPS 服務器給出 400 Bad Request

Question

我使用 io.undertow.core 設置了 Java HTTPS 服務器，創建了 HttpListener，看起來我的代碼很完美，但是......它不起作用。 它會根據任何請求給我 400 Bad Request。

下面是undertow相關的代碼，http等：

package ru.epserv.epmodule.modules.serverapi;

import org.bukkit.Bukkit;
import org.json.simple.JSONObject;

import io.undertow.Undertow;
import io.undertow.server.HttpHandler;
import io.undertow.server.HttpServerExchange;
import ru.epserv.epmodule.modules.serverapi.contexts.BanwhyContext;
import ru.epserv.epmodule.modules.serverapi.contexts.FirstseenContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetPlayerContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetPlayersContext;
import ru.epserv.epmodule.modules.serverapi.contexts.GetWarningsContext;
import ru.epserv.epmodule.modules.serverapi.contexts.IsOnlineContext;

public class HTTPSServer {

    public static String notFound;
    public Undertow server;

    @SuppressWarnings("unchecked")
    public void start() {
        JSONObject notFoundJSON = new JSONObject();
        notFoundJSON.put("response", null);
        notFoundJSON.put("error", "not_found");

        HTTPSServer.notFound = notFoundJSON.toJSONString();

        Ping ping = new Ping();

        this.server = Undertow.builder()
                .addHttpsListener(45105, "0.0.0.0", HTTPSServer.getSSLContextFromLetsEncrypt())
                .setHandler(new HttpHandler() {

                    @Override
                    public void handleRequest(final HttpServerExchange t) throws Exception {
                        ParsedRequest r = new ParsedRequest(t);
                        r.setResponseHeader("Access-Control-Allow-Origin", "*");
                        Bukkit.getLogger().warning(r.getRequestURI().getPath());
                        switch (r.getRequestURI().getPath().substring(1).trim()) {

                            break;
                        case "firstseen":
                            firstseen.handle(r, t);
                            break;
                        case "lastseen":
                            lastseen.handle(r, t);
                            break;
                        case "timeplayed":
                            timeplayed.handle(r, t);
                            break;
                        case "banwhy":

                        default:

                            r.write(HTTPSServer.notFound);
                            r.send();
                        }
                    }
                })
                .build();
        this.server.start();
    }

    public void stop() {
        server.stop();
    }

}

我還嘗試使用curl -v --data "" https://mc.epserv.ru:45105/list獲取更多信息，這是 output：

我嘗試使用AccessLogHandler 、 RequestDumpingHandler ，但什么也沒有，Undertow 不記錄任何內容並繼續響應 400 Bad Request。

我究竟做錯了什么？ 我發現了一個錯誤還是什么？ 怎么了？ 如果需要，請向我詢問更多信息，如果我的英語不好，抱歉

問題已解決 - 我使用mvn install （來自https://github.com/undertow-io/undertow repo）再次構建了 Undertow，現在它按預期工作了。 這可能是 Undertow 2.1.2.Final-SNAPSHOT 的錯誤，但在 Undertow 2.1.4.Final-SNAPSHOT 上一切正常。
